CC -!- FUNCTION: Part of the high-affinity ATP-driven potassium transport CC (or Kdp) system, which catalyzes the hydrolysis of ATP coupled CC with the electrogenic transport of potassium into the cytoplasm. CC This subunit is responsible for energy coupling to the transport CC system. {ECO:0000256|HAMAP-Rule:MF_00285, CC ECO:0000256|SAAS:SAAS00822527}. CC -!- CATALYTIC ACTIVITY: ATP + H(2)O + K(+)(Out) = ADP + phosphate + CC K(+)(In). {ECO:0000256|HAMAP-Rule:MF_00285, CC ECO:0000256|SAAS:SAAS00822523}. CC -!- SUBUNIT: The system is composed of three essential subunits: KdpA, CC KdpB and KdpC. {ECO:0000256|HAMAP-Rule:MF_00285, CC ECO:0000256|SAAS:SAAS00822521}. CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP- CC Rule:MF_00285}; Multi-pass membrane protein {ECO:0000256|HAMAP- CC Rule:MF_00285}. CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC CC 3.A.3) family. Type IA subfamily. {ECO:0000256|HAMAP- CC Rule:MF_00285, ECO:0000256|SAAS:SAAS00822561}. CC -!- CAUTION: The sequence shown here is derived from an CC EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is CC preliminary data. {ECO:0000313|EMBL:ESL83116.1}.
